10 Claims.

My invention relates broadly to revolvin doors, and more particularly to a construction of stabilizing journal for revolving doors.

One of the objects of my invention is to provide a simplified construction of mounting means for revolving doors for facilitating installation and removal of the revolving doors.

Another object of my invention is to provide a construction of stabilizing journal for revolving doors having means for pivoting the revolving door structure on a stationary pintle, with means for retracting the pintle for facilitating installation or removal of the revolving door structure.

Still another object of my invention is to provide a simplified form of abutment for the inwardly directed peripheral edges of the revolving doors in a revolving door assembly.

A further object of my invention is to provide a retractible pintle for revolving doors having means for maintaining the pintle in either projected or retracted position.

A still further object of my invention is to provide a ball race mounting disposed within the tubular shaft structure of a revolving door for reducing frictional resistance and facilitating rotation of the door structure.

A further object of my invention is to provide a construction of spring actuated pintle for journaling a revolving door structure, in which a spring means is subjected to slight compression when the pintle is moved into position in a supporting bushing, and maintained under compression for yieldably maintaining said pintle in place and the revolving door in operative position.

Other and further objects of my invention reside in the construction of revolving door hardware and stabilizing journal, as set forth more fully in the following specification by reference to the accompanying drawings; in which:

3; Fig. 9 is a detail horizontal section taken on line 99 of Fig. 3; Fig. 10 is a transverse vertical section through the step bearing and a portion of the stabilizing journal, taken substantially on 10 line ill-46 of Fig. 3; Fig. 11 is a side elevation partly in section, of the stabilizing journal, Fig. 12 is a side elevation with parts broken away and in section, disclosing one of the members used in association with my improved stabilizing journal; Fig. 13 is a detail top plan view'of a portion of the step bearing; and Fig. 14 is a transverse vertical section taken on line I4l4 of Fig. 13.

Referring to the drawings in detail, reference characters I and 2 designate sleeve members disposed centrally of the vertically extending tubular shaft 10. The sleeve members I and 2 are interconnected by a coupling member 3 which is riveted within the sleeve members i and 2 by means of rivets 28. Sleeve member 2 is connected adjacent the upper portion thereof through the bolt member 2| having a circular head which is free to shift vertically and rotate within sleeve 2. Bolt member 2| passes through the upper end of sleeve 2 but is confined therein within the limits defined by the depth of the sleeve and the abutment offered by the coupling member 3. A coil spring 23 is disposed concentrically about bolt 2| and located between the upper extremity of sleeve 2 and the lower face of slidable member 4.

A rivet 29 extends through slidable member 4 and the upper end of bolt 2! for securing the bolt member 2| in rigid connection with respect to slidable member A. The slidable member 4 has a finger engaging member 5 connected therewith through bolt 19, as shown, and projecting laterally therefrom. In order that the hardware may be assembled readily, I provide a work aperture 36 in the tubular shaft l0 through which a screw driver may be introduced in securing screw IS in position in slidable member 4 for anchoring the finger engaging member 5 in position. The upper portion of the slidable member 4 has a laterally disposed recess 6 therein which receives the sleeve 32. Both the sleeve 32 and the finger engaging member 5 project through a longitudinally disposed slot 30 in the tubular shaft I0.

I provide a metallic shaft covering designated generally at l3 which is secured to tubular shaft in any suitable manner such as by means of rivets 35. The construction of the metallic shaft covering [3 is illustrated more particularly in Figs. 8 and 9. The metallic shaft covering I 3 is substantially in the form of a Geneva cross, that is to say, the metallic shaft covering l3 has four plane surfaces which substantially define elements of a rectangle interconnected by arcuate recessed portions which serve as longitudinally extending seats for the inwardly directed edges of the doors 42. The longitudinally extending arcuate shaped recesses form relatively tight seals with respect to the inwardly directed peripheral edges of doors 42. The metallic shaft covering I3 is so constructed adjacent the finger engaging member that finger engaging member 5 projects through the slot 3! in covering 13. Slot 3| extends for a vertical distance slightly greater than the limits of movement of the finger engaging member 5. The covering I3 is apertured at 33 and 34 to receive the end of the detent I. The detent 1 is shaped in the form of a reciprocatory plunger mounted in laterally extending sleeve 32 against the action of spring 22. As finger engaging member 5 is moved upwardly, detent l is retracted against the action of spring 22 and is thus withdrawn from aperture 34 and, when elevated to a position in alignment with aperture 33 is projected into aperture 33, as represented in Fig. 4 for maintaining the finger engaging member 5 and its associated parts, as hereinafter described, in elevated position.

It will be seen that the head bolt 2| is free to move rotatively within sleeve 2 and is also capable of limited translatory movement with respect to sleeve 2.

A somewhat different arrangement is provided in establishing a, connection with sleeve member I. The bolt member has the circular head thereof confined within sleeve l with the bolt member 20 free to rotate. A connection is provided between the lower end of bolt member 20 and the shaft 9. Shaft 9 is recessed at the upper extremity, as indicated at 90 and is laterally apertured at 9b. The end of bolt 20 fits into socket 9c and is pinned in position therein by means of rivet 21 which passes through the apertures 9b in the end of shaft 9 and through the lower extremity of bolt 20. A ball race comprising a pair of separable guides and a multiple arrangement of ball bearings is provided. This ball race and ball bearing unit constitutes a thrust bearing 24 which is located in a recess la in the lower extremity of the sleeve 1. The thrust bearing 24 provides an anti-friction means for supporting the thrust of spring 23 and allowing easy rotation of part 9. This spring pressure is continuously exerted to provide a means for holding part 8 into part Hi. This action compensates for any change in the bearing. a

A pintle 8 is provided between the lower extremity of shaft 9 and a floor bearing. The pin- -tle 8 has a frusto-conical end portion which projects into a frusto-conical seat [8a in the journal plate l8. The journal plate I8 is supported in a horizontal position in the bearing support l5 which is embedded in the floor structure designated generally at 45. Screw members [80 extend through apertures |8d in journal plate l8 and are secured in screw-threaded recesses 3a in bearing support I6. The journal plate l8 has a centrally depending portion through which the lateral aperture 18b extends, providing a mounting means for the laterally extending pin 26 which extends diametrically across the frustoconical seat I8a. The lower end of the pintle 8 is diametrically slotted, as shown at 8b by which pintle 8 is prevented from rotating. Pintle 8 is stationary and forms a support for stationary shaft 9 through the agency of the socket 8c in the extremity of the pintle and the lateral apertures 8d therein through which rivet member may be projected. For this purpose, shaft 9 is apertured at its lower extremity, as indicated at 9a and the said apertured portion aligned with apertures 8d in socket 8c allowing rivet 25 to be passed therethrough for interlocking pintle 8 with shaft 9. The portion of pintle 8, shown at 6a, is shaped to receive the sleeve H which is supported at its lower periphery by means of shoulder Be on pintle 8. The tubular shaft I0 is internally recessed at its lower end, as indicated at [9b. There is sufiicient depth provided in the internal recess lDb at the lower end of the tubular shaft IE to allow sleeve bearing H to be shifted upwardly as pintle 8 is retracted and disengaged from the laterally extending pin 26. The manner of retracting the pintle 8 is shown more clearly in Fig. 4. By reason of the journal mounting of tubular shaft ID on sleeve bearing I! at the bottom of the door, extreme precision in operation of the revolving door may be maintained.

In order to provide for the support of revolving doors 42 by the vertically extending tubular shaft H], I provide key-ways 31 and 38 in the tubular shaft I 0, as shown more particularly in Figs. 5 and 6. Key-ways 31 and 38 are located adjacent the opposite end of tubular shaft Ill therein, each adapted to receive keys 39 which interlock the revolving door hardware shown generally at 40 with the tubular shaft [0. The revolving door hardware 40 carries the hangers H which support the doors 42 in the general arrangement shown in Figs. 1 and 2.

It will be observed that the spring 23 is at all times under slight compression. Pintle 8 is projected downwardly, by movement of finger engaging member 5, to the position shown in Fig. 3, (Page 6). When the finger engaging memher 5 is actuated by a vertical upward movement for the purpose of retracting pintle 8, spring 23 is maintained under slight compression by reason of the narrow limits of movement afforded to the head of bolt 2| between the upper end of sleeve 2 and the abutment established. by coupling member 3. The installation or the removal of the revolving door becomes an extremeby simple matter when using the stabilizing journal of my invention as a minimum number of operations to collapse the doors and shift the doors into or out of position are necessary. The rotation afforded by the shaft 9 interconnecting bolt 20 and sleeve member I, and the rotation permitted by the sleeve 2 and bolt member 2| is sufficient to insure rotation of the revolving doors with a high degree of precision and balance.

I have found the revolving door hardware of my invention highly practical in its construction. While I have described my invention in one of its preferred embodiments, I realize that modifications may be made and, accordingly, I intend no limitations upon my invention other than may be imposed by the scope of the appended claims.
